SPECIFICATION forming part of Letters Patent No. 360,245, dated March 29, 1857.

Application filed September 2. 1886. Serial No. 212,491. (No model.)

To @ZZ whom, it may concern:

Be it known that 1, DUANE T. PnRKrNs, a citizen of theUnited States, residing at Springield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Hydrants, of which the following is a specification.

This invention relates to improvements in hydrants; and the invention consists in the peculiar construction and arrangement of the inletegate thereof and the waste devices connected therewith, all as hereinafter fully described, and set forth in the claim.

In the drawings forming part of this specification, Figure 1 is a side elevation, partly in section, of the lower or receiving end of a hydrant constructed according to my invention, its upright discharging-pipe and gaterod being shown broken'o, and the position of the gate when opened being shown in dotted lines. Fig. 2 is a perspective View of the gate and of the waste device removed from the hydrant.

In the drawings, 2 indicates in a vertical sectional view the lower end of the hydrantshell or gate case having on one side the inlet-nozzle 3, to receive the end 4C of a suitable water-main. Around the border of the inlet, on the inner side ofthe case 2, is formed a pro-l jecting gate-seat, 5, having its face finished at an incline to a vertical line through the hydrant, as shown. A wastehole, 6, is formed in the bottoni of said case, and on one side thereof are cast two supports, 7, in which is hung, as below described, a Vwasteplug, by which said hole is closed and opened. On the upper side of case 2 is formed a suitable flanged outlet, to which is bolted in the usual manner an upright pipe, 9, which extends above the surface of the ground, and is provided with the usual outlet-connections. The said gate case is made of cast-iron, and, owing to the below-described manner of constructing a gate therefor, the face of the gateseat 5 docs not require to be faced with -brass or other noncorrosive metal, as heretofore generally practiced, and hence very little expense is incurred in fitting said case to receive the gate.

The hydrant-gate (shown in side elevation in Fig. 1 and in perspective View in Fig. 2) is likewise made of cast-iron, having a perforation in one end, through which a bolt, l2,

passes, by which it is pivoted to the case 2. The hollow projection 13 on the case, in which the end of the gate is pivoted, has two boltholes therein, which receive the ends of the bolt 12, and the latter is either riveted or fastened to the case by suitable nuts screwed to the ends thereof, whereby said gate is suitably secured to the case and has a free vibratory motion on said bolt.

The face of the gate 10 is provided with a circular recess, as shown in dotted lines in Fig. 1, in which is secureda disk, 14, of wood, by suitable screws or otherwise, which disk constitutes the bearing-face of the gate, which, as hereinafter described, by impingement against the face of the gateseat 5, shuts the inlet to the hydrant, the face of the gate being formed at an incline corresponding to that of said seat. By employing a disk of wood for the gate-face instead of making the latter of metal, as is usually done, the considerable expense of fitting the latter to its seat is obviated, and the nature of said wooden face permits it to be so forced against the gate-seat as to sink the latter more or less into the surface ofthe face, thereby making a good water-tightjoint, and in case of necessity said face-disk 14 may be replaced ata very slight cost.

The gate 10 is provided with two bolt-sup ports, 15, on its upper side, to which is secured the lower end of the gate-rod 1G, a bolt, 17, passing through said supports and an eye in the end of said rod, whereby the latter has a pivotal connection with the gate, and its upper end extends to the upper end of the pipe 9, and has an ordinary nut-connection with the latter, whereby it is given a suitable vertical motion to operate the gate to open and close the latter, the dotted, lines in Fig. 1 indicating the open position of the gate. Other suitable yielding substance than wood may be used for the face-disk 14.

To automatically discharge the water from the hyd-rant after the gate has been shut, and to shut the waste-hole of the hydrant when the gate is opened, the metallic waste-plug 17 is provided. Said plug is hung in a vertical position on the inner side of the case 2, near to the side of the gate in said supports 7, its lower end being adapted to close the wastehole 6, and its upper end having secured thereto a metallic weight, 1S, said weight proxo ing freezing in cold weather.

`jecting sufciently toward the gate to extend somewhat over its upper side, as shown in Fig. 2, whereby the latter, when lifted up, engages with the lower end of said weight and lifts the 5 latter and said plug to the position shown in Fig. 1, thereby opening the waste-hole 6, letting any Water that remains in the hydrant after the gate has been opened and closed freely escape through said waste-hole, thus prevent- When the gate swings down, as indicated by dotted lines in Fig. l, to let water ow into and through the hydrant through pipe 4, it swings away from Weight 18 and leaves the latter and the plug I 5 17 connected thereto free to drop by gravitation and close said wastehole.
